Paper Abstract

Two promising post-processing techniques, i.e. applying tensile strain and rising temperature, are demonstrated to enhance mode-coupling efficiency in the CO2-laser-carved long period fiber grating with periodic grooves. Such two post-processing techniques can be used to enhance the resonant attenuation of the grating to achieve a LPFG-based filter with an extremely large attenuation and to tailor the transmission spectrum of the grating to exactly equalize the gain of erbium-doped fiber amplifiers.
